MORRIS PRINTING AND STITCHING MACHINE Filed July 24, 192a a Sheets-Sheet a mvzrn'oa Patented June 2, 1931 UNITED STATES PATENT OFFICE EDWARD THOMAS MORRIS, OF LONDON, ENGLAND, ASSIGNOR TO B. & CO. INC., OF NEW YORK, N. Y., A CORPORATION OF NEW YORK PRINTING AND STITCHING MACHINE Application filed July 24, 1926, Serial No. 124,736, and in Great Britain September 7, 1925.

The object of this invention is to prevent the operation of the staple forming plunger of a stitching machine forming part of a printing machine, when it is not desired to stitch.

\ In the usual arrangement the staple forming plunger is operated by means such as a roller which travels in a circular path and is in contact for a portion of its travel with a cam which embraces a portion only of the shaft about which the roller moves.

According to this invention meansv are provided for rendering the cam inoperative.

In one way of carrying out the invention the cam is carried by a hmged bracket, having teeth formed thereon, which are engaged by a worm so arranged that the cam can be moved into or out of operative position. The cam, when in action, can be locked in position by a bolt.

Preferably a stop is provided against which the bracket comes when the cam is brought into its operative position.

In the drawings Figures 1, 2 and 3 are end views, partly in section and partly broken away, showing the mechanism in different positions, the views being taken on line A-B of Figure 4 looking in the direction of the arrows A, the dotted line construction of Figures 2 and 3 being taken on line X-Y of Figure 4 looking in the direction of the arrows B, and

Figure 4 is a plan view of the construction shown in Figures 1, 2 and 3.

In the accompanying drawings, which illustrate the invention, 1 is a frame rotatably mounted in which are two cylinders 2, 3, the cylinder 2 being provided with staple forming plungers 4 of the usual construction, such as disclosed, for instance, in the patent to Church No. 993,649, dated May 30, 1911, each of which is operable by a lever 5 secured to a shaft 6 adapted to be rocked by a lever 7 which is provided with a roller 8. 9 is a fixed cam surface and 10 is a cam surface formed on a plate 11 secured to a bracket 11 pivoted at 12 to the frame 1, the brackets being provided with teeth 13 in mesh with a worm 14 fast with a spindle 15- ro- 50 tatably mounted in a bearing 16 and providvided with'a projection 20 adapted when the cam is in the operative position to engage a fixed stop 21. The stitching wire 1s indicated at 22, and 23 are guides of usual construction in which as a short length of wire is moved through them the two ends of the wire are first upturned at right angles and are then inturned.

In operation when it is desired to stitch the web passing between the cylinders 2, 3, the cam surface 10 is moved into the position shown in Fig. 1 of the drawings, whereby as the cylinder 2 revolves the roller 8 is moved by its engagement with the cam surfaces 9, 10, whereby the lever 7, shaft 6 and lever 5, are rocked so that the stitching plunger 4 is moved into a position for picking up a length of stitching wire 22, which is then moved by the plunger 4 between the guides 23, and finally is forced through the web by the rolling contact of the cylinders. The roller 8 is then out of engagement with the cam-surfaces 9, 10, and a spring 25 rocks the lever 7, shaft 6 and lever 5, whereby the staple forming plunger 4 is moved towards the centre of'the cylinder 2. 7

When it is desired not to stitch the web, the handwheel 17 is rotated and the bracket 11 is rocked upon its pivot 12, whereby the cam surface 10 is moved into a position such that it is not engaged by the roller 8, so that thelever 5 is not operated to move the staple V forming plunger 4 into a position for picking up a length of stitching wire 22, this posi tion of the parts being shown in Fig. 3.

What I claim is 1. In stitching apparatus for printing machines, the combination of a cam, a staple- ,forming plunger operable by said cam, and

means for moving said cam out of operative position to render said staple forming plunger wholly inoperative for an indefinite period.

2. In a stitching machine, the combination of a pivoted bracket, a cam on said bracket, a staple forming plunger operable by said cam, teeth on said bracket, and a Worm engaging said teeth.

3. In a stitching machine, the combination of a cam, a staple forming plunger operable by said cam, means for moving the cam into and out of operative position, means for limiting movement of said cam, and means for locking said cam in position.

4. In a stitching machine, the combination of a pivoted bracket, a cam on said bracket, a staple forming plunger operable by said cam, teeth on said bracket, a Worm engaging said teeth, means for limiting movement ofsaid bracket, and means for locking said bracket inposition. I

5. In a stitching machine, the combination of a frame, a pair of cylinders mounted thereon, means for rotating said cylinders, a staple forming plunger mounted on one of said cylinders, a cam pivotally mbunted on said frame and adapted to operate said plunger, and means for moving said cam into and out of operativeposition.

6. In a stitching machine the combination of a frame, a pair of cylinders mounted thereon, means for rotating said cylinders, a staple forming plunger mounted on one of said cylinders, a bracket pivotally mounted on said frame, a cam on said bracket adapted to operate said plunger, teeth on said bracket, and a Worm engaging said teeth. I

7. In a stitching machine, the combination of a frame, a pair of cylinders mounted thereon, means for rotating said cylinders, a staple forming plunger mounted on one of said cylinders, a bracket pivotally mounted on said frame, a cam on said bracket adaptedto operate said plunger, teeth on said bracket, a worm engaging said teeth, means for limiting the movement of the said bracket, and means for locking said bracket in position.

8. In astitching machine, the combination of a frame, a pair of cylinders mounted thereon, means for rotating said cylinders, a staple forming plunger mounted on one of said cylinders, a cam pivotally mounted on said frame and adapted to operate said plunger, means for moving said cam into andout of operative position, means for limiting the movement of said cam, and means for locking said cam in position. 7

In testimony that I claim the foregoing as my invention I have signed my name this 13th day of July, 1926.
